Arachnida. 



greenish tinge; the tarsal and metatarsal joints being pale murky 

 yellowish. 



Falces short, stout, and inclined towards the maxillae. Their colour 

 is a rich dark brown. 



Maxillae and labium of a pale murky brown, palest at the ex- 

 tremities. 



I have described this distinctly marked and very active species 

 from an immature female, kindly given me alive by Mr. Samuel 

 Stevens, who captured it in August, 1862, among orchideous plants 

 in the conservatory of Mr. G. Read, at Burnham, near Bridgewater, 

 Somerset. Mr. Stevens says it was of frequent occurrence there, and 

 was cherished by Mr. Read on account of its services in destroying 

 insects injurious to his plants. He conjectured that it might have 

 been imported from South America among some of his plants. This 

 may have been so ; still, as it appears to be of an undescribed species, 

 and has nothing particularly foreign aljout its appearance, I have de- 

 scribed it as a British spider, leaving it to future observations to de- 

 termine whether it is an imported species or not. 



Salticus cocco-ciltatus. 



Male, adult. Length 1-tenth of an inch. Length of cephalothorax 

 1-eighteenth. Relative length of legs, 4, 3, 1, 2. 



Cephalothorax oblong and massive, sloping abruptly behind. Colour 

 dull yellow-brown, with a reddish hue, obscurely mottled with 

 fine blackish spots. The margins are clouded with] blackish. 

 The square bounded by the eyes jet-black, and continued in a 

 tapering form to the hinder margin ; it is thinly clothed with 

 red and blackish hairs. The four eyes of the front row are sur- 

 rounded with a sort of iris, or cilia of bright scarlet sessile 

 hairs ; this iris is broadest on the lower margins of the eyes, 

 and gives the spider a very remarkable appearance. 



Eyes eight, forming three sides of a square ; the front side slightly 

 curved ; the sides straight. The two central eyes of the front 

 row are very much larger than that on either side, and the space 

 between them is rather wider than that between each and the 

 outer eye on its side. The intermediate eyes of the side rows 

 are much the smallest, and they are equidistant from the other 

 two eyes of the row, and in the same straight line. 



Legs moderately long, very stout and strong; clothed, but not very . 

 thickly, with black and yellowish hairs, and black spines. The
